Abstract
The invention discloses a top cover of a bicycle handle beam tube. A spot-faced hole is formed in the center of the upper portion of the top cover, a convex body is arranged on the periphery of the bottom of the top cover, and an annular groove is formed along the periphery of the convex body and the shape of the upper portion of the top cover. Therefore, the top cover is light, few in adopted materials and low in cost.
Description
Technical field
The present invention relates to top cover, relate in particular to a kind of top cover of bicycle handle beam tube.
Background technology
It is made that the top cover of existing bicycle handle beam tube is generally metal material, considers its weight and material cost actuarial to some extent for what stress now lightweight and economy, and therefore cost is higher, uneconomical practicality.
Summary of the invention
The top cover that the object of the invention is to be to provide a kind of bicycle handle beam tube, quality is light, and materials are few, and cost is low.
According to an aspect of the present invention, provide a kind of top cover of bicycle handle beam tube, top cover central upper portion is established fish eyelet, and bottom peripheral edge is provided with convex body, is provided with annular groove along this convex body periphery and the appearance of top cover top.
In some embodiments: top cover material is aluminum alloy.
The present invention is simple in structure, easy to operate, and quality is light, and materials are few, and cost is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the top cover of a kind of bicycle handle beam tube of the present invention.
Fig. 2 is the section drawing of the top cover of a kind of bicycle handle beam tube of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing explanation, the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of top cover of bicycle handle beam tube, top cover 10 central upper portion are established fish eyelet 11, and bottom peripheral edge is provided with convex body 12, is provided with annular groove 13, to save materials and expendable weight along these convex body 12 peripheries and the appearance of top cover top.
Wherein this top cover material is aluminum alloy, is processed by forging, and with regard to structural strength, this top cover is enough to reach the bolt required intensity that locks to forge the density that produced.
This top cover is placed in handle bundle pipe 20 and locks with bolt 40 with front fork tube 30 suit places, and this intensity and expendable weight all can get a desired effect.
In sum, the present invention is simple in structure, easy to operate, and quality is light, and materials are few, and cost is low.
The above is only one embodiment of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
